GetParametersByPath

Request results are returned on a best-effort basis. If you specify MaxResults
in the request, the response includes information up to the limit specified. The number
of items
returned, however, can be between zero and the value of MaxResults. If the service
reaches an internal limit while processing the results, it stops the operation and
returns the
matching values up to that point and a NextToken. You can specify the
NextToken in a subsequent call to get the next set of results.

The hierarchy for the parameter. Hierarchies start with a forward slash (/) and end
with the
parameter name. A parameter name hierarchy can have a maximum of 15 levels. Here is
an example of
a hierarchy: /Finance/Prod/IAD/WinServ2016/license33

If a user has access to a path, then the user can access all levels of that path.
For
example, if a user has permission to access path /a, then the user can also access
/a/b. Even if a user has explicitly been denied access in IAM for parameter
/a/b, they can still call the GetParametersByPath API action recursively for
/a and view /a/b.
